Retired computer programmer Mr. Norrie is believed to be in care and Northern Irishman Anderson, of Gateshead Road, Borehamwood was arrested while showcasing the vacant property.

He pleaded guilty to two counts of fraud by false representation, namely impersonating the homeowner, between November 18 and December 22, last year and on February 17, this year.

He also admitted possessing an identity document, with intent, namely a counterfeit passport in the name of Mr. Norrie on February 17, the day of his arrest.

“It takes a lot of nerve,” announced Judge Peter Clarke QC.

A concerned neighbour tipped-off Mr. Norrie’s ex-wife about groups of people visiting the house and a silent alarm was fitted, leading police to Anderson when he was there hosting prospective buyers.

Victim: Charles Norrie

Anderson claims he was merely the frontman and was only going to receive a few hundred pounds after answering an online Craigslist ad offering “no questions asked” work to a suitable white, middle-aged gent.

He spun a tale to buyers of wanting a quick sale of between £1.0-£1.2m because he and his wife were divorcing.
